PIPE-SHIELD.

:To all whom it mag conceive:

Be it known that I, ;JOHN"N. DART, a citizen of the United States, and residentof Richmond, in the county of Henrico and State of Virginia, have inventedcertainnew and useful Improvements in Pipe-Shields,-

of which the following'is a specification.

My invention relates to tobacco .pipes, and is directed to an improved shield for the mouth of thepipe' bowl.

A principal object of my invention is to provide a shield-which will protect the pipe 'from'the e'fiects ofwind,-thereby adapting it for use out of doors, and especiallyby automobilists. In. the preferred' form thetobacco will also be protected. against-rain.

A further object 1s to provide a pipe which will facilitate even and rapid'combu'stion of the tobacco without sacrificing adequate-protection from the elements. 7

urthermore,--I-have provided a shield so constructed :that the pipe may be lighted when the shield is closed, and if desired the "shield may-be so proportioned thatit will provide Eprotection for the match from wind and'rain'. I

-A further object is-to= rovide'a shield that :free access to substantially theentire bowl of the pipe at any time without diminishingrthe protective effect of theshield. 1

Another object-isto provide anefficient shield without vemloying the unsightly and pipe equipped witha shield embodying my invention is not only neat andattractive in .but' :is'v sufiiciently -.-compact to permit it to be carried in the pocket or even 7 iplaced in anordinary case without di-fliculty. 40

.also 'attainaan .object which is important In-the preferred constructionshown, I

' fromthecommercialpoint ofview, as the type of tshiel'd disclosed. is readily constructed from a single;sheetof-metal-by a very simple process and whether constructed from a single "par ly -shield is sosimple-and strong that it will sheet or from two .or.1;more connected-to each other, the

indicated in dotted lines,

advantage in permitting Figure lis aperspective'view of apipe through a portion of the pipe'bowl and shield, the open position of. the 'shieldrbeing and Fig. 3..is a planview of the shield and mounting. 'j

Upon the pipe bowl 10. is mounted the ,shield or cover embodying my invention,

which includes a body 11 preferablyslightly convex and having an outer edge extending along substanti ally the entire upper edge of .the pipe bowl.

Centrally of the body 11 there is formed or mounted a concave hood 12 having a laterally directed-opening 13 communicatingwith the insideof the pipe bowl. The hood may obviously vary consid- ,erably in size and she e, the general object being to so proportion the hood thata free passage of substantial area throughout will be provided between thebowl of the pipe and the outer air; tratecl have been found suitable, audit will be noted that in this type the margin of the hood12 is located entirely within body 11, though the hood and body together cover substantially the entire top of the pipe.

I have also found that byprovid-ing a draft substantially from thewcenter of-the' .pipe the tobacco will burn more readily and evenly, so that the employment of a shield does not, substantially interfere with smoking. 1 This object has been accomplishedby locating .the opening 13 fairly nearthe center of the pipe, and shaping the'hood 12 so that the draftthrough opening 13 will be approximately central. By suitably shaping the top of hood 12to give it a slope downwardly to the left as shown in Fig. 2, the opening 13 maybe located somewhat to the right of the center in order to provide ample draft at the right point. This arrangement furthermore permits'an openin o f-the maximum size without weakening t e body 11 of the shield. This feature has a further the .user to light .the pipe readily while the The proportions ill'us shield is closed,

as a match maybe inserted through the opening, or the flame suckedinto it and over a considerable area ofthe tobacco.

The front edge 14 of hood 12 adjacent the opening 13 is preferably close to vertical en a in a suitable alinement with the adjacent edge 15 of the shield body, to prevent the entrance of any substantial amount of rain through the opening when the shield is closed. In'the form shown edge 14 of the hood is inclined slightly; but this is not essential as the edges of opening 13 can be located to provide'any amount of protection against the entrance of rain through the opening.

I preferably form hood l2 integral with body 11, and they may both be formed from a single sheet of metal by'means of simple dies. Howev r, it is apparent that this construction, while highly convenient, may be varied without departure from the invention.

The shield may be mounted on the pipe bowl in various ways, but it is important that it be readily removable to provide access to the entire bowl. F or this purpose it is convenient to employ a ferrule 15 mounted about the upper edge of the pipe and connected byv hinge 16 to the shield. At the opposite side of the shield from the hinge I may employ a latch 14 of any type, the one illustrated having a latch tongue 18 projection 19 on the ferrule 15, and provided with an out-turned lower tip 20 which forms a finger piece for releasing the latch and throwing back the cover. has been found convenient, especially when the pipe is used by automobilists, to have the hood 12 directed rearwardly,

' and to arrange the hinge and latchfso that Fig. 2,

the cover will swing up away from the smoker; but these features may obviously be varied, both as to the direction of the hood and the location of the hinge and latch elements.

. When the smoker desires to fill his pipe, the-shield may be thrown backward on hinge 16 into position shown in dotted lines in giving as complete access to the bowl of the pipe as is obtained where no shield is used. After filling, the pipe may be lighted with the shield in this position, or if wind or rain makes this inadvisable, the

pipe may be lighted either with the shield slightly elevated to form a guard against the wind, or with the shield entirelydown,

as above noted. Hood 12 will divert wind.

' blowing across the pipe away from the open ing even though the wind should be blowing across the pipe. instead of directly in the face of the user; and when the wind is at the back of the user his head will afford adequate protection. As a matter of fact, the dead air spaces in the pipe pre vent serious disturbance even if the wind should blow in such a direction asto enter the opening '13.

Moreover, the hood is shaped so that a wind will not produce un due draft on the pipe, though it does not interfere with smoking, this object being at tamed by the streamline curves of the hood which cause the least disturbance in air passing over it.

I am aware that numerous other shields for pipes have heretofore been employed, some of which embody certain ofthe objects heretofore indicated; but none of the shields heretofore known accomplishes all the objects in a single construction, and certain features of my invention are believed to be absolutely novel in and of themselves.

While I have shown and described a preferred embodiment of my invention and indicated certain variations, it will'be apparent that numerous other changes -may be made by one skilled in the art within the scope of my invention as lowing claims. H

I claim: H

1. A pipe shield adapted to cover substantially the entire bowl of the pipe, and

including an inclined hood terminating at set forth in the fola draft opening spaced throughout from the edges of the shield and bowl. 7

2. A pipe shield adapted to coversubstantially the entire bowl of the 'pipe, and in eluding an inclined hood terminatingfat a draft opening adjacent the center of the bowl spaced throughout from the edges of the shield and bowl.

3. A pipe shield including a hood portion terminating in a substantially vertical draft opening. and a marginal portion entirely 5. A pipe shield including ahoodportion terminating in a substantially vertical draft opening, and a marginal portlon ent rely surrounding said hood -port1on and opening and overlving the top of the bowl. said hood 7 and marginal portions being formed from a single sheet of metal.

' 6. A pipe shield including a hood portion terminating in a substantially vertical draft opening. and a marginal portion entirely surrounding said hood, portion .and opening and overlying the top of'the bowl,

to permit the shield to be shifted entirely clear of'the pipeibowl mouth.

7. A pipe shield including a hood portion and means for connecting the shield to a pipe adapted terminating in a substantially ,vertical draft opening, and a marginal portion entirely surrounding said hood portion and opening and overlying-the top of the bowl, a'support adapted to be connected, to'the pipe bowl,

and a hinge connection between said support and shield, whereby the shieldmay be swung entirely clear of the bowl mouth."

8. A smoking pipe having a shield pivotally attached to the bowl of the pipe, and adapted to cover the mouth thereof, said shield consisting of a disk-like member having a transverse slit or incision, the material of the disk-like member in rear of the said slit or incision being upset to provide a raised hood terminating at a substantially vertical draft-opening facing in the direction of the stem of the pipe. 7
